//! \ingroup OpenMaya MFn
//! \brief Component list function set for dependency node data.
/*!
MFnComponentListData allows the creation and manipulation of component list
(represented as MObjects) data objects for use in the dependency graph.

If a user written dependency node either accepts or produces MObjects
containing component lists, then this class is used to extract or
create the data that comes from or goes to other dependency graph
nodes.  To access it, the MDataHandle::data method is used to get an
MObject for the data and this should then be used to initialize an
instance of MFnComponentListData.
